Host-Side and Disk Array Parameters:

- Host-Side Parameters -

Maximum Queued I/O Count
: This function allows you to configure the maximum number of I/O queue the controller can accept from the host computer.

LUNs per Host SCSI ID: This determines how many LUN numbers will be available with each host bus ID. The maximum number per ID is 32.

Login Authentication with CHAP: This option allows you to enable or disable the login authentication with the Challenge Handshake Authentication Protocol (CHAP) function. CHAP enables the username and password to be encrypted against eavesdroppers. (Note: This function is only applicable on EonStor iSCSI series RAID subsystems.)

 

- Disk Array Parameters -

Rebuild Priority: This determines how much system resources is conducted when rebuilding a logical drive. The default setting of the rebuild priority is “LOW.” Rebuild will have smaller impact on host I/O access, but rebuild will take a longer time to complete. Changing the rebuild priority to a higher level you will have a faster rebuild, but will certainly increase the Host I/O response time. The default setting “LOW”
is recommended.

Write Verify on Normal Access: Errors may occur when a hard drive writes data. To avoid the write
error, the controller can force hard drives to verify written data. This select box lets the sybsystem perform Verify-after-Write during normal I/Os.

Write Verify on LD Rebuild: This select box lets the sybsystem perform Verify-after-Write when rebuilding a logical drive.

Write Verify on LD Initialization: This select box lets the sybsystem perform Verify-after-Write when initializing logical drives.

Maximum Drive Response Timeout(ms): Select a maximum drive response timeout period.

AV Optimization Mode: The AV optimization is applied for the emerging Audio/Vidwo or non-drop frame applications.
